Descriptions

The LAN-side Web-Configuration Interface has Stack-based Buffer Overflow vulnerability in the D-Link Wi-Fi router firmware DIR-890L DIR890LA1_FW107b09.bin and previous versions. The function created at 0x17958 of /htdocs/cgibin will call sprintf without checking the length of strings in parameters given by HTTP header and can be controlled by users easily.
